Restart SharePoint Services on SharePoint 2010 farm

Step 1. Create a folder with 2 powershell blank files as below image.

Step 2. Open Sam.Functions.PS1 file and copy the below code snippet.

 # Stop specified service on all servers within the farm
function Stop-ServiceOnFarm
{
    param ($ServiceName)
   
    foreach ($server in (Get-SPServer | Where {$_.Role -ne "Invalid"}) )
    {
        $service = Get-WmiObject -computer $server.Name Win32_Service -Filter "Name='$($ServiceName)'"
       
        if ($service -eq $null -or $service.State -eq "Stopped") {
            continue
        }
       
        Write-Host "Stopping '$($ServiceName)' on $($server.Name)..."
        $service.InvokeMethod('StopService',$Null)
       
        do {
            Start-Sleep -s 5
            $service = Get-WmiObject -computer $server.Name Win32_Service -Filter "Name='$($ServiceName)'"   
        } while ($service.State -ne "Stopped")
    }  
}

# Starts specified service on all servers within the farm
function Start-ServiceOnFarm
{
    param ($ServiceName)
   
     foreach ($server in (Get-SPServer | Where {$_.Role -ne "Invalid"}) )
     {
        $service = Get-WmiObject -computer $server.Name Win32_Service -Filter "Name='$($ServiceName)'"
       
        if ($service -eq $null -or $service.State -eq "Started" -or $service.State -eq "Starting") {
            continue
        }
       
        Write-Host "Starting '$($ServiceName)' on $($server.Name)..."
        $service.InvokeMethod('StartService',$Null)
     }
}

# Restarts specified service on all servers within the farm
function Restart-ServiceOnFarm
{
    param ($ServiceName)
   
    Stop-ServiceOnFarm $ServiceName
    Start-ServiceOnFarm $ServiceName
}

# Restarts SharePoint Services on all servers within the farm
function Restart-TimerandAdminService
{
    Restart-ServiceOnFarm "SPTimerV4"
    Restart-ServiceOnFarm "SPAdminV4"

}

Step 3. Open the file Sam.RestartAdmin-TimerServicesOnFarm and copy the below snippet. 
if ($SCRIPT:scriptDir -eq $null -or $SCRIPT:scriptDir -eq "")
{
 $SCRIPT:scriptDir = (Get-Location -PSProvider FileSystem).ProviderPath
}

# ** Load My functions
Write-Host "* Loading Functions..."
. (Join-Path $scriptDir "Sam.Functions.ps1")

Restart-TimerandAdminService

Step 4. Close and Save the files and execute the .\Sam.RestartAdmin-TimerServicesOnFarm.ps1 file from any server in the farm.

Restart IIS in all servers in a SharePoint 2010 farm

Step 1. Create a folder with 2 powershell blank files as below image.

 

Step 2. Open Sam.Functions.PS1 file and copy the below code snippet.

# Stop specified service on all servers within the farm

function Stop-ServiceOnFarm

{

    param ($ServiceName)

     

    foreach ($server in (Get-SPServer | Where {$_.Role -ne "Invalid"}) )

    {

        $service = Get-WmiObject -computer $server.Name Win32_Service -Filter "Name='$($ServiceName)'"

         

        if ($service -eq $null -or $service.State -eq "Stopped") {

            continue

        }

         

        Write-Host "Stopping '$($ServiceName)' on $($server.Name)..."

        $service.InvokeMethod('StopService',$Null)

         

        do {

            Start-Sleep -s 5

            $service = Get-WmiObject -computer $server.Name Win32_Service -Filter "Name='$($ServiceName)'"   

        } while ($service.State -ne "Stopped")

    }  

}

# Starts specified service on all servers within the farm

function Start-ServiceOnFarm

{

    param ($ServiceName)

     

     foreach ($server in (Get-SPServer | Where {$_.Role -ne "Invalid"}) )

     {

        if ($service -eq $null -or $service.State -eq "Started" -or $service.State -eq "Starting") {

            continue

        }

         

        Write-Host "Starting '$($ServiceName)' on $($server.Name)..."

        $service.InvokeMethod('StartService',$Null)

     }

}

# Restarts IIS on all servers within the farm

function Restart-IIS

{

    Stop-ServiceOnFarm "W3SVC"

    Stop-ServiceOnFarm "SMTPSVC"

    Stop-ServiceOnFarm "IISADMIN"

     

   Start-ServiceOnFarm "IISADMIN"

   Start-ServiceOnFarm "SMTPSVC"

   Start-ServiceOnFarm "W3SVC"

}

 

Step 3. Open the file Sam.RestartIISOnFarm and copy the below snippet.

 

  if ($SCRIPT:scriptDir -eq $null -or $SCRIPT:scriptDir -eq "")

{

 $SCRIPT:scriptDir = (Get-Location -PSProvider FileSystem).ProviderPath

}

# ** Load My functions

Write-Host "* Loading Functions..."

. (Join-Path $scriptDir "Sam.Functions.ps1")

Restart-IIS

Step 4. Close and Save the files and call the .\Sam.RestartIISOnFarm.ps1 file from any server in the farm.

Merge SharePoint Log files in a farm

As we know that SharePoint logs are generated in all servers in a farm. So if you would like to find the log for your application issue, you may need to look into the log in all WFE/Index servers. In that case you do not need to open logfile from each server rather you can use Merge-SPLogFile powershell command in one server to get the ULS logs for the entire farm and investigate it.

Example:

Once the logfile got generated and you can open in UlsViewer tool to epen the logfile.

One intersting thing is that you can also filter logfiles by specifying ‘second’ duration in the command. This is really required as thousands of logs got created in a minute.
